Background technology
Excavator bucket teeth is the important easily consumption component on excavator, similar to the tooth of people, is made of toothholder and crown
Dipper Teeth, the two by axis pin connect, since bucket tooth wear out failure part is crown, as long as replace crown, bucket tooth work
Make face and be in contact with being mined thing, different working stage its stressing conditions differences, crown in a complete mining process
Position first contacting material surface when, due to speed, bucket tooth nose part is subject to stronger impact, if the surrender of bucket tooth is strong
Spend low, it will produce plastic deformation in tip, with the increasing of excavating depth, bucket tooth stressing conditions can change, and work as bucket tooth
When cutting material, relative motion occurs for bucket tooth and material, and very big forward extrusion power is produced on surface, thus in bucket tooth working face and
Larger frictional force is produced between material, bucket tooth component good or not influences the length of the service life of bucket tooth, is produced in failure
During play a major role, present major part bucket tooth only focuses on material and have ignored stressing conditions so that bucket tooth
Loss does not improve, it is therefore desirable to often replaces bucket tooth, nowadays replacement process is difficult to replace because getting rusty or blocking mostly.
